Question

Which among the following is not an advantage of using cyclostationary feature detection?

a.

Better performance than energy detection

b.

Does not require prior knowledge of the signal transmitted by the primary user

c.

Robust noise performance

d.

Rapid attainment of high processing gain

Posted under Cognitive Radio

Answer: (d).Rapid attainment of high processing gain Explanation:The primary advantage of using cyclostationary feature detection is its ability to differentiate noise signals from modulated signals. This is due to incorporated redundancy in modulated signals. However cyclostationary feature detection is computationally intensive and demands long observation time.
